Maximum Likelihood Estimation ∗ Clayton

This module introduces the maximum likelihood estimator. We show how the MLE implements the likelihood principle. Methods for computing th MLE are covered. Properties of the MLE are discussed including asymptotic e ciency and invariance under reparameterization. The maximum likelihood estimator (MLE) is an alternative to the minimum variance unbiased estimator (MVUE). For many estimation proble...

Reply to Christensen and Christensen and to Malter: Pitfalls of erroneous analyses of hurricanes names.

Our article (1) reports evidence for a relationship between femininity of hurricane names and fatality rates, along with experimental evidence that female-named storms elicit lower risk perceptions and preparedness intentions. In response, Malter (2) cites some bloggers’ critiques about inclusion of hurricanes from the era of female-only names, interpretation of results, and external validity o...

W.D. Christensen and C.A. Hooker

Donald Campbell has long advocated a naturalist epistemology based on a general selection theory, with the scope of knowledge restricted to vicarious adaptive processes. But being a vicariant is problematic because it involves an unexplained epistemic relation. We argue that this relation is to be explicated organisationally in terms of the regulation of behaviour and internal state by the vica...
